How much weight can the HOXWELL jack block handle?

Will it fit my trailer’s jack, stabilizer or post?

Yes — the HOXWELL jack block is made for universal compatibility. Its footprint and top-saddle design accept most tongue jacks, feet, posts and round, square or scissor stabilizers for flexible use across many RV types.

How do stacking and portability improve campsite setup?
